Curb and Gutter Form, of which the fol-.

lowing 1s a specification.

The device forming the subject matter of this application, adapted to be employed in the formationof curbs and the like. r

The invention aims to provide a molding structure which may be employed without preparing and grading the sub-structure or foundation, upon which the molding structure is adapted to rest.

A further object of the invention is to provide a novel means for assembling the division plate with the front and back plates; to provide novel means for removin the division plates; and to provide nove means for assembling the intermediate plate with the front plate.

With the foregoing and other objects in view which will appear as the description roceeds, 'the invention resides in the comination and arrangement of parts and in of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the in-' ventio In the accompanying drawings,Figure 1 shows the invention in fperspective; Fig.

In carrying out the invention there' is provided a back plate ,1, having a rectangularly disposed upper flange '2, a parallel bottom flange 3, and a lip 4, depending from the upper flange 2, substantially parallel to the back plate proper 1. The invention further includes an intermediate plate denoted b the numeral 5, the same having an upper flange 6 outstanding therefrom, the

intermediate plate being provided with 9. depending lip 7, ordinarily substantially parallel to the plate proper 5. The lower edge of the late 5 is curved or otherwise shaped, as s own at 8, to fashion the desired an le in the curbing.

The rent plate is denoted by the numeral 9, and is provided with an outstanding upper flange 10, with a parallel lower flange 11, and with a lip 12, depending from the flan e 10. The flanges 2 and 10,

are reinforce respectively, by the lips 4 and 12. The invention further includes a division plate, denoted en er-ally by the numeral 14 in Fig. 1. T18 division plate 14 embraces an upright body portion 15, and an outstanding arm 16, defining in the upper edge of the division plate, an angle '17, in which the intermediate plate 5 fits, as

clearly shown in Fi 1.

V In order to assem le the division plate 15, removably, with the .back plate 1 and with the front plate 9, the division plate 14 is upwardly notched, in its lower ed e, adjacent both ends, as shown at 18, to de e depending fingers 19. Through the division plate 14, adjacent its upper corners, pins 20 are inserted, or lateral projectitns are formed upon the plates 14, at the places indicated by the ins 20, in any other desired manner. The ack plate 1 and the front plate 9 have openings in their upper edges, ada ted to receive the fingers 19. In Fig. 4, a re mental perspective of the back plate 1 1s shown and a description of these openings will be confined to the back late, it being understood that they apply with equal propriety to the front plate 9.

In the flange 2 of the back plate 1 there is fashioned a curvilinear recess 21. This curvilinear recess 21 tends but part way through theflange 2, as Fig. 6 will render evident. The recess 21 communicates with a narrowed slot 22, extended through the flange 2, and carried downwardly into and through the body portion of the plate 1, as shown at 23. The fingers 19 of the division plate 14 are inserted into the slots 22 in the plates 1 and 9, the fingers of the plates. The pins or other re ections 20 may rest in the recesses 21. Tiiedivision plate 14 willthus be upheld, but in order to revent its lower edge from swinging about, liosses 24 are stamped, or formed otherwise the plates lend 9, below the portions 23 of 19 engaging back the slots inthe plates 1' and 9. Between the bosses 24, the divisionplate 14 is, obvi ously, adapted to fit.

To the forward face of the intermediate plate 5, angle brackets are secured. To

these an le brackets 25, the rear'ends of connecting are 26 are ivoted, the bars having at their forward en s, depending fingers 27, adapted to register in the slots 22 of the front plate 9, and to engage with the front face of the front plate, the intermediate plate 5 being thus assembled with the front plate 9.

In practical operation, the stakes 28 and 5 29 are driven into. the earth, to grade, and to line, the stakes 28 and 29 being notched, in their upper edges, as shown at 30, and at 31, The flange 2 of the back plate 1 rests upon the tops of the stakes 28, and the dezo ending lip 1 registers in the notches 30, the ower flanges 3 resting against the forward faces of the stakes 28. It is to be noted that the flange 2 is considerably wider than the flange 3, and thus the stakes 28 may be driven vertically into the earth, and when the back plate 1 is assembled with the stakes 28, the back plate will stand in vertical position. Similarly, the flanges 10 of the front plates 9 rest upon the tops of the stakes 29, 30 the depending lips 12 registering iii the notches 3i, and the lower flanges 11 hearing. against the rear faces of the stakes 29. The flange 10 is wider than the flan e 11, for the purpose hereinhefore set fort The division plates are then mounted in place, in

the plates 1 and 9, in the manner hereinbefore set forth, and cinders or the like, form- 'mg a sub-structure, are placed, together with the concrete, and tamped, the interme- 40 diate plate 5 being connected with the front plate 9 in the manner hereinbefore described. It is to be noted, referring particu larly to Fig. 2, and noting the dotted line 32 which represents the lower edge of the 46 vision plate 14, that tin lower edge of the division plate is spaced slightly'above the lowenedges of the plates 1 and 9. Thus, the concrete will be permitted to amalgamate, below the division plate 14, it, of course, be- 50 ing understood that the division plates are removed before the concrete has taken a final set. i

It frequently happens that the stakes 28 and 29 heave in the ground, and carry with them, the back plate 1., the front plate 9, the 'division plate 14 and the intermediate plate '5. If the molded structure consists of a series of separated blocks, these blocks will be moved out of alinement, more or less, by the 60 heaving of the stakes. In the present instance, the moldcd structurenv ll not be thus distorted, for the reason that the concrete will coalesce below the lower edges of the division plate 14, thereby causing themolded 86 structure to be fashioned in a continuous plate; an intermediate length, the molded structure being of sulficient weight so that itcannot be moved by a heaving of the stakes; as would take place if the molded structure consisted of a series of relatively small, individually formed, separated blocks.

It will be seen readily that the plates 1, 5 and 9 are so positioned that a straight edge may be run along their flanges, to strike off the finished material.

\Vhen it is desired to remove the division plates 14, a hook (not shown) may be" inserted into the seats or openin s 21, to cm gage with the .pins 20, theli ting of the division lates 14 being thus accomplished without iificult Having thus d escribed the invention, what is claimed is:

1. A device of the class described comprising a back plate; a front plate; a division plate terminally connected, removably, with the front plate and the back plate, the division plate consisting of an arm, and' a bed upstanding from the arm, adjacent the bee ate resting u on the upper edge of the div1sicn' plate an abutting against the body portion of the division plate; and means for removably securing the intermediate plate'to the front plate.

2.
